Review on 🌀 High-Speed Brushless DC Cooling Fan 24V 40mm x 40mm x 10mm - Ideal for 3D Printers, Humidifiers, Aromatherapy, and Small Appliances (2-Pack) by Bill Dooley

I was trying to find a fan that moves enough air and runs smooth and quiet. This is this fan. The fan runs at 100% on a 24 volt system. You can listen to the noise and hear how quiet it is and see the napkin strip she moves. The printing speed was 12 mm/s. I really like these fans and now I have backups. Most of the noise you hear comes from the power supply fan, which is located to the right of the printer.
